Description

Membrana revestida apropiada para ser utilizada en particular como lona de protección.Coated membrane suitable for use in particular as a protective canvas.

La presente invención se refiere a una membrana revestida destinada a ser utilizada en particular como lona de protección.The present invention relates to a membrane coated intended to be used in particular as a canvas protection.

La invención está vinculada al campo de las membranas técnicas y, más precisamente, de los materiales textiles recubiertos que pueden ser utilizados como lonas de protección, por ejemplo para equipar vagones de transporte ferroviario, cisternas flexibles o tanques destinados a contener líquidos agresivos, o incluso pantallas de protección sometidas a un entorno severo.The invention is linked to the field of technical membranes and, more precisely, of textile materials coated that can be used as protective tarpaulins, by example for equipping railroad cars, tanks flexible or tanks intended to contain aggressive liquids, or even protection screens subjected to a severe environment.

Más particularmente, la invención prevé una nueva estructura de membrana que posee al mismo tiempo una buena resistencia a las condiciones atmosféricas o fisicoquímicas agresivas, al mismo tiempo que conserva una capacidad para ser ensamblada mediante los procedimientos de termosoldadura estándar y con un coste satisfactorio.More particularly, the invention provides a new membrane structure that at the same time has a good resistance to atmospheric or physicochemical conditions aggressive, while retaining an ability to be assembled using standard heat welding procedures and With a satisfactory cost.

Estado de la técnicaState of the art

En el campo de las lonas, por ejemplo para equipar vagones de transporte ferroviario o cisternas flexibles, se emplean muy corrientemente unos materiales textiles recubiertos de un material a base de policloruro de vinilo (PVC), tal como se describe en el documento FR 2 305 301. Estos materiales textiles recubiertos de PVC presentan la ventaja de poder ensamblarse fácilmente mediante termosoldadura para permitir la confección adaptada a la forma a realizar.In the field of canvases, for example for equip rail transport cars or flexible tanks, se they very commonly use textile materials coated with a material based on polyvinyl chloride (PVC), as described in document FR 2 305 301. These textile materials PVC coated have the advantage of being assembled easily by heat welding to allow sewing adapted to the way to perform.

No obstante, los materiales textiles recubiertos de PVC adolecen de ciertos inconvenientes, en particular cuando se someten a condiciones exteriores severas. Así, un material textil recubierto de PVC sometido a una temperatura particularmente baja tiene el riesgo de ver degradarse con el tiempo su capa de recubrimiento, desapareciendo así, por tanto, las propiedades de estanqueidad que son buscadas para equipar por ejemplo vagones de transporte ferroviario. De la misma manera, se observa una degradación de las capas de recubrimiento de PVC cuando éstas se someten a temperaturas elevadas o se exponen a atmósferas químicas corrosivas.However, coated textile materials PVC suffer from certain disadvantages, particularly when subject to severe exterior conditions. Thus, a textile material PVC coated subjected to a particularly low temperature you have the risk of seeing your layer of degradation over time coating, thus disappearing, therefore, the properties of tightness that are sought to equip for example wagons of railway transport. In the same way, a degradation of the PVC coating layers when they are subject to high temperatures or are exposed to chemical atmospheres corrosive

Este tipo de lona puede someterse asimismo a tensiones específicas propias de aplicaciones particulares. Así, en el caso en que se emplean las lonas sobre remolques de transporte ferroviario, el material textil recubierto se somete a los chorros de chispas consecutivas a los malos contactos del pantógrafo sobre la catenaria de alimentación eléctrica. Estas chispas se acompañan de proyecciones de partículas de metal en fusión que vienen a degradar la capa de recubrimiento al quemarla, formando así un orificio en la lona. Por tanto, la lona ya no es estanca y esto puede generar riesgos de degradación de las mercancías transportadas.This type of canvas can also undergo specific tensions specific to particular applications. So in the case in which tarpaulins are used on transport trailers railway, the coated textile material is subjected to jets from consecutive sparks to bad pantograph contacts on the power supply catenary. These sparks are accompanied of projections of melting metal particles that come to degrade the coating layer when burned, thus forming a hole in the canvas. Therefore, the canvas is no longer waterproof and this can generate risks of degradation of the goods transported

Se ha propuesto ya realizar las lonas de vagones ferroviarios utilizando materiales textiles a base de hilos resistentes al calor y en particular de fibras de aramida. Estas lonas poseen una mejor resistencia a las particular de metal en fusión, pero adolecen en cambio de los inconvenientes de tener un coste elevado y de ser excesivamente rígidas, lo que impide doblarlas fácilmente, en particular al nivel de las zonas de fuelle cuando las lonas son rebatidas para la carga del remolque.It has already been proposed to make the tarpaulins of wagons railway using textile materials based on threads heat resistant and in particular aramid fibers. These tarps have a better resistance to the particular metal in fusion, but suffer instead of the inconvenience of having a high cost and of being excessively rigid, which prevents fold them easily, particularly at the level of the bellows zones when tarpaulins are refuted for trailer loading.

En el caso particular de camiones destinados al transporte de materiales bituminosos para realizar los revestimientos de calzada, es necesario utilizar unas lonas a fin de impedir que estos materiales se enfríen demasiado rápidamente. Esta exposición al calor y a una atmósfera químicamente reactiva con el PVC provoca asimismo una degradación rápida de la lona.In the particular case of trucks destined for transport of bituminous materials to perform road coverings, it is necessary to use some tarps in order to prevent these materials from cooling too quickly. This exposure to heat and a chemically reactive atmosphere with PVC also causes rapid degradation of the canvas.

Las lonas de protección se utilizan asimismo por ejemplo como pantalla de protección para equipos de soldadura al arco. La exposición a la radiación ultravioleta y sobre todo a las proyecciones de materiales en fusión, genera degradaciones y perforaciones de estas pantallas que ya no cumplen entonces su función esencial.Protective tarps are also used by example as protection screen for welding equipment arc. Exposure to ultraviolet radiation and especially to melting material projections, generates degradations and perforations of these screens that no longer meet then their essential function

Para resolver estos inconvenientes, se han propuesto ya unas membranas revestidas de silicona en cada una de las dos caras, pero estas membranas únicamente pueden ensamblarse mediante procedimientos de costura o por encolado, procedimientos que adolecen de numerosos inconvenientes, respectivamente la pérdida de estanqueidad y la imposibilidad de garantizar la calidad del ensamblaje por encolado.To solve these problems, they have already proposed silicone coated membranes in each of both sides, but these membranes can only be assembled by sewing procedures or by gluing, procedures that suffer from numerous inconveniences, respectively the loss sealing and the impossibility of guaranteeing the quality of gluing assembly.

Se conoce a partir del documento DE-43.04.079 una multicapa que comprende una banda de soporte en material textil que presenta, en una de sus caras un material de PVC flexible e ignífugo y en la otra de sus caras un material elastómero termoplástico o reticulado.It is known from the document DE-43.04.079 a multilayer comprising a band of support in textile material that presents, on one of its faces a flexible and flame retardant PVC material and on the other of its faces a thermoplastic or crosslinked elastomeric material.

Aunque esta multicapa presenta propiedades antifuego y propiedades de resistencias mecánicas, no podrá sin embargo resistir entornos químicos particularmente corrosivos. La capa de elastómero será atacada progresivamente y se fisurará y degradará progresivamente, dejando de esta manera el alma textil sin protección y, por tanto, susceptible asimismo de deteriorarse.Although this multilayer has properties fireproof and mechanical resistance properties, you can not without However resist particularly corrosive chemical environments. The elastomer layer will be attacked progressively and will crack and will degrade progressively, leaving the textile soul without protection and, therefore, also susceptible to deterioration.

Se conoce asimismo a partir de los documentos EP-0 374 776 y EP-0 450 144 un aparato respiratorio con una caperuza realizada con una multicapa que comprende un alma de material textil resistente a los desgarrones realizado con fibras de vidrio. Está previsto un revestimiento de PVC sobre una cara del material textil y un revestimiento de silicona, eventualmente asociado con un promotor de adhesión, sobre la otra cara del material textil.It is also known from the documents EP-0 374 776 and EP-0 450 144 a respiratory system with a hood made with a multilayer comprising a soul of textile material resistant to Tears made with glass fibers. It is planned a PVC coating on one side of the textile material and a silicone coating, possibly associated with a promoter of adhesion, on the other side of the textile material.

Sin embargo, este tipo de multicapa que además es relativamente costoso, está reservado a aplicaciones muy particulares y específicas que no necesitan superficies importantes de material textil que forma el alma de soporte. Además, en caso de choques mecánicos que conduzcan a desgarrones de una u otra de las capas exteriores, las fibras de vidrio liberadas constituirán un peligro potencial para la piel y las mucosas del usuario, así como para el entorno.However, this type of multilayer that also It is relatively expensive, it is reserved for very applications particular and specific that do not need important surfaces of textile material that forms the support soul. In addition, in case of mechanical shocks that lead to tears of one or the other of the outer layers, the released glass fibers will constitute a potential danger to the user's skin and mucous membranes, as well as for the environment

Exposición de la invenciónExhibition of the invention

El objetivo de la invención es proporcionar una membrana que pueda ser utilizada para la fabricación de lonas diversas y que, por tanto, presente propiedades de soldabilidad mediante las técnicas corrientes (altas frecuencias, ultrasonidos, aire caliente, hierro caliente), así como propiedades de resistencia a la temperatura y a atmósferas corrosivas o, más generalmente, agresivas, y ello conservando una flexibilidad necesaria para la manipulación fácil. Un segundo problema planteado es la realización de superficies importantes para lonas de protección diversas pasando asimismo por etapas de confección textil.The object of the invention is to provide a membrane that can be used for canvas manufacturing diverse and, therefore, present weldability properties by current techniques (high frequencies, ultrasound, hot air, hot iron), as well as resistance properties at temperature and corrosive atmospheres or, more generally, aggressive, and this while retaining the necessary flexibility for easy handling A second problem is the realization of important surfaces for various protective tarpaulins also going through textile manufacturing stages.

Por tanto, la presente invención se refiere a una membrana revestida, apropiada para ser utilizada en particular como lona de protección. Una membrana de este tipo comprende un alma de soporte textil y un revestimiento sobre cada una de sus caras. El material textil se elige a base de hilos de poliéster y/o de poliamida.Therefore, the present invention relates to a coated membrane, suitable for use in particular As a protective canvas. Such a membrane comprises a soul of textile support and a coating on each of its faces. The textile material is chosen based on polyester threads and / or polyamide.

Según la invención, la primera de sus caras está revestida de un material a base de policloruro de vinilo, mientras que la segunda de sus caras está revestida de un material a base de silicona.According to the invention, the first of its faces is coated with a material based on polyvinyl chloride, while that the second of its faces is covered with a material based on silicone.

Dicho de otra manera, la invención consiste en realizar una membrana híbrida, que comprende materiales diferentes de una cara a la otra, de tal modo que la primera capa realizada por ejemplo a base de PVC puede soldarse fácilmente a paneles adyacentes, realizados a partir del mismo material. La segunda cara está revestida de un material a base de silicona y presenta, por su parte, una excelente resistencia a las temperaturas muy altas y muy bajas, así como de forma general a las atmósferas químicas que provocan la degradación del PVC. Por tanto, esta membrana híbrida combina al mismo tiempo buenas capacidades para la confección por termosoldadura, con una excelente resistencia a las condiciones de temperatura y, más generalmente del entorno exterior severo o agresivo.In other words, the invention consists in make a hybrid membrane, comprising different materials from one side to the other, so that the first layer made by PVC-based example can be easily welded to panels adjacent, made from the same material. The second face It is covered with a silicone-based material and has, due to its part, excellent resistance to very high temperatures and very low as well as in general to the chemical atmospheres that cause the degradation of PVC. Therefore, this hybrid membrane combines at the same time good capacities for the preparation by heat welding, with excellent resistance to the conditions of temperature and, more generally of the severe outside environment or aggressive.

En una primera forma de realización, el alma de soporte textil puede estar compuesta por una tela tejida. En una segunda forma de realización, el alma de soporte textil puede estar compuesta por una tela no tejida.In a first embodiment, the soul of Textile support can be composed of a woven fabric. In a second embodiment, the textile support core may be Composed of a non-woven fabric.

Para realizar este tipo de membrana, se ha destacado que convenía tomar precauciones técnicas y operativas para evitar que el PVC esté en contacto con los materiales de silicona, con el riesgo de ver aparecer zonas de no conformidad y una falta de adhesión de los revestimientos al alma de la membrana, ya sea ésta de telas tejidas o de telas no tejidas. Esta es la razón por la cual se ha destacado en un modo de realización privilegiado que el alma de la membrana debe asegurar una estanqueidad al paso de los materiales de superficie que son incompatibles entre ellos. Esta estanqueidad se obtiene mediante una tejedura suficientemente tupida en el caso de un alma de tela tejida, o suficientemente densa en el caso de un alma de tela no tejida.To perform this type of membrane, it has been highlighted that it was convenient to take technical and operational precautions to prevent PVC from being in contact with the materials of silicone, with the risk of seeing areas of nonconformity appear and a lack of adhesion of the coatings to the membrane core, either this one of woven fabrics or nonwoven fabrics. This is the reason why it has stood out in one embodiment privileged that the soul of the membrane must ensure a tightness of the surface materials that are Incompatible between them. This tightness is obtained by a sufficiently dense weave in the case of a cloth soul woven, or sufficiently dense in the case of a cloth soul not woven

En un modo de realización particular, se preferirá utilizar materiales de silicona del tipo recubrimiento sin disolvente, lo que permite recubrir previamente el soporte y depositar después una capa de recubrimiento de PVC.In a particular embodiment, it is prefer to use silicone materials of the coating type without solvent, which allows the support to be previously coated and then deposit a layer of PVC coating.

En la práctica, este material de silicona elegido puede estar comprendido en la familia de las siliconas elastómeras vulcanizables por hidrosililación (que es una reacción de poliadición), en particular del tipo bicomponente.In practice, this silicone material chosen can be included in the family of silicones Vulcanizable elastomers by hydrosilylation (which is a reaction polyaddition), in particular of the two-component type.

Este tipo de material textil recubierto puede ser utilizado en múltiples aplicaciones, en particular como lonas de protección, por ejemplo para equipar vagones de transporte ferroviario, cisternas flexibles o tanques destinados a contener líquidos agresivos, o incluso pantallas de protección sometidas a un entorno severo.This type of coated textile material can be used in multiple applications, particularly as tarpaulins protection, for example to equip transport wagons railway, flexible tanks or tanks intended to contain aggressive liquids, or even protective screens subjected to a severe environment.

La invención se comprenderá mejor y sus diversas ventajas y diferentes características se pondrán más claramente de manifiesto a partir de la descripción siguiente del ejemplo no limitativo de realización.The invention will be better understood and its various advantages and different characteristics will be made more clearly than manifest from the following description of the example no performance limitation.
